Real-number DFT codes on a fading channel

The utilization of real-number DFT codes for a multiplicative channel is introduced. By the proposed encoding procedure, some redundancies can be added into the transmitted data. With these redundancies, syndromes for the parameters of a fading channel can be obtained from the received data. The decoding algorithm for real-number DFT codes can be used to calculate the fading parameters with these syndromes.
